[0055] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0056] The present application aims to at least solve the technical problem of high energy consumption of vehicle-mounted air conditioners in the related art. To this end, the present application proposes a vehicle body structure and a vehicle, which can improve the energy consumption of the thermal management of the vehicle-mounted air conditioner by installing an energy storage device.

[0057] The following refers to Figures 1-7 Describe the vehicle body structure 1 according to an embodiment of the present application.

[0058] As Figures 1-4 shown, the vehicle body structure 1 includes an outer covering 11 and an energy storage structure 10 installed inside the outer covering 11. The energy storage structure 10 includes: a thermal insulation layer 110, an energy storage device 120, an energy storage heat exchanger 140, and a heat insulation member 150.

[0059] The outer covering 11 is the outermost layer of the vehicle body structure 1 and is usually made of metal, plastic, or composite materials. Its main function is to protect the internal structure of the vehicle body from the external environment, such as wind, rain, impact, etc.

[0060] The thermal insulation layer 110 is installed inside the outer covering 11. Its main function is to reduce the heat exchange between the inside of the vehicle and the external environment and maintain the stability of the vehicle interior temperature. The material of the thermal insulation layer 110 usually has good heat insulation performance, such as foam plastic, aerogel, etc.

[0061] The energy storage device 120 is one of the core components in the vehicle body structure 1. An accommodation cavity for accommodating an energy storage medium 130 is formed inside the energy storage device 120. The energy storage medium 130 can be a heat storage medium or a cold storage medium, depending on the design requirements of the vehicle. The function of the energy storage device 120 is to release the stored energy when the vehicle needs it to support the driving of the vehicle or provide the energy required for other functions.

[0062] The energy storage heat exchanger 140 is installed inside the energy storage device 120. A heat exchange medium flow channel is formed inside the energy storage heat exchanger 140. The heat exchange medium flow channel is used to allow a heat exchange medium to flow through, such as water, oil, or other heat conduction media, and perform heat exchange with the energy storage medium 130. Through the inlet and outlet of the heat exchange medium, a heat exchanger, such as an engine cooling system or an air conditioning system, can be connected to the energy storage heat exchanger 140 to achieve energy transfer and conversion.

[0063] The heat insulation member 150 is a component that is installed inside the energy accumulator 120 in an openable and closable manner. The main function of the heat insulation member 150 is to reduce the heat exchange between the energy accumulator 120 and the external environment. When using the energy accumulator 120, the heat insulation member 150 can be opened to increase the heat exchange efficiency. When the heat insulation member 150 is opened, the energy storage medium 130 in the energy accumulator 120 exchanges heat with the passenger compartment by means of thermal radiation, thereby adjusting the temperature in the passenger compartment. When the energy storage medium 130 is a heat storage medium, the temperature in the passenger compartment can be increased. When the energy storage medium 130 is a cold storage medium, the temperature in the passenger compartment can be decreased. When maintaining the temperature of the energy accumulator 120 stable, the heat insulation member 150 is closed to reduce heat loss, thereby improving the flexibility and efficiency of energy storage and conversion.

[0064] The heat insulation member 150 can be an openable and closable rigid structure or an openable and closable flexible structure. The openable and closable rigid structure can include an openable plastic plate, louvers, and a push-pull structure. The openable and closable flexible structure can include a roller shutter and a foldable structure.

[0065] In the related art, in high-temperature and low-temperature working conditions, the energy consumption of the vehicle air conditioner will increase significantly, affecting the vehicle's cruising range and having a greater impact on the driving and riding experience. In this application, an energy storage device that can be used for cold storage or heat storage is added to the vehicle system, and at the same time, a radiation temperature control technology is introduced, thereby improving the thermal management energy consumption of the vehicle air conditioner and enhancing the driving and riding comfort.

[0066] According to the vehicle body structure 1 provided by the embodiment of the present application, the energy storage structure 10 can achieve efficient energy storage and management by integrating components such as the thermal insulation layer 110, the energy accumulator 120, the energy storage heat exchanger 140, and the heat insulation member 150. By the heat insulation member 150 that is installed inside the energy accumulator 120 in an openable and closable manner, the conversion of energy in the energy storage structure 10 can be controlled according to the actual use situation, thereby reducing the energy consumption of the vehicle and improving the cruising range of the vehicle.

[0067] In some embodiments, as Figure 1 shown, the energy storage structure 10 further includes: a heat conduction structure 160, which is installed between the energy accumulator 120 and the heat insulation member 150.

[0068] The heat conduction structure 160 is located between the energy accumulator 120 and the heat insulation member 150. Its main function is to efficiently transfer heat between the energy accumulator 120 and the heat insulation member 150. When the energy in the energy accumulator 120 needs to be utilized or released, the heat conduction structure 160 can quickly and evenly transfer the heat to the external environment.

[0069] The heat conduction structure 160 is usually made of materials with high heat conduction performance, such as copper, aluminum, or composite materials with excellent heat conduction performance, to help heat transfer quickly inside the heat conduction structure 160, reduce energy loss. At the connection points of the heat conduction structure 160 with the energy accumulator 120 and the heat insulation member 150, effective sealing measures can be taken to prevent energy leakage. The heat insulation member 150 can also provide good heat insulation effect in the closed state to reduce unnecessary heat loss.

[0070] When releasing the energy in the energy accumulator 120, the heat conduction structure 160 starts to work. At this time, the heat insulation member 150 opens, and heat is quickly transferred to the external environment through the heat conduction structure 160, realizing the conversion and utilization of energy.

[0071] It can be understood that by controlling the heat conduction performance of the heat conduction structure 160, precise adjustment of the temperature inside the energy accumulator 120 can be achieved, which helps to keep the energy storage medium 130 within the optimal working temperature range, thereby improving the energy storage and conversion efficiency.

[0072] In some embodiments, as Figure 1 shown, the heat conduction structure 160 includes: a temperature equalizing member 161 and a heat transfer member 162.

[0073] The main function of the temperature equalizing member 161 is to balance or evenly distribute the temperature, usually used to reduce the temperature gradient and improve the thermal stability of the system. The temperature equalizing member 161 is installed inside the energy accumulator 120, and can exchange heat with the energy storage medium 130 inside the energy accumulator 120 more effectively, for balancing the temperature inside the energy accumulator 120. The heat transfer member 162 is clamped between the temperature equalizing member 161 and the energy accumulator 120, that is, the heat transfer member 162 plays a bridging role between the temperature equalizing member 161 and the energy accumulator 120, enabling heat to be effectively transferred from the energy accumulator 120 to the temperature equalizing member 161.

[0074] The heat insulation member 150 can be selectively used to shield the temperature equalizing member 161, and can reduce heat transfer when needed. The main function of the heat insulation member 150 is to reduce the heat exchange between the energy accumulator 120 and the external environment. When using the energy accumulator 120, the heat insulation member 150 can be opened to increase the heat exchange efficiency. When the heat insulation member 150 is opened, heat is transferred from the energy accumulator 120 through the heat transfer member 162 to the temperature equalizing member 161, and the temperature equalizing member 161 exchanges heat with the passenger compartment by means of thermal radiation, thereby adjusting the temperature inside the passenger compartment. When the energy storage medium 130 is a heat storage medium, the temperature inside the passenger compartment can be increased; when the energy storage medium 130 is a cold storage medium, the temperature inside the passenger compartment can be decreased. When keeping the temperature of the energy accumulator 120 stable, the heat insulation member 150 is closed to reduce heat loss.

[0075] It can be understood that heat is transferred in sequence through the accumulator 120, the heat transfer member 162, and the temperature equalizing member 161. The temperature equalizing member 161 exchanges heat with the occupant compartment by means of thermal radiation, thereby realizing the energy transfer between the energy storage structure 10 and the outside world.

[0076] In some embodiments, such as Figure 1 shown, the energy storage heat exchanger 140 includes multiple sections bent and arranged in the accommodation cavity.

[0077] The accumulator 120 can store and release heat within a certain period of time. An accommodation cavity for accommodating the energy storage medium 130 is formed inside the accumulator 120. The energy storage heat exchanger 140 includes multiple sections bent and arranged in the accommodation cavity. Specifically, heat exchange elements, such as heat exchange tubes or fins, are bent multiple times in the accommodation cavity. This bent arrangement can increase the contact area between the heat exchange elements and the surrounding energy storage medium 130, thereby improving the heat exchange efficiency. At the same time, the fluid flowing through the multiple sections bent and arranged in the energy storage heat exchanger 140 spends a longer time, can absorb or release more heat, and helps to increase the thermal energy storage capacity of the energy storage heat exchanger 140 in the accommodation cavity.

[0078] It can be understood that the bent arrangement can help optimize the structure of the energy storage heat exchanger 140 and keep the fluid at an appropriate flow rate and temperature distribution when flowing through the multiple sections, thereby achieving the best heat exchange effect.

[0079] In some embodiments, the energy storage heat exchanger 140 has fins located in the accommodation cavity.

[0080] Fins are thin sheets or structures attached to heat exchange elements, such as heat exchange tubes or plates, aiming to increase the heat exchange surface area, thereby improving the heat exchange efficiency. The energy storage heat exchanger 140 has fins located in the accommodation cavity. The energy storage medium 130 in the accommodation cavity is in direct contact with the fins, which can increase the contact area between the energy storage heat exchanger 140 and the energy storage medium 130, thereby improving the heat exchange efficiency. In the energy storage heat exchanger 140, the fins can be installed on heat exchange elements with various shapes and configurations to achieve the best heat exchange effect and thermal energy storage capacity.

[0081] It can be understood that by providing fins in the accommodation cavity, the contact area between the energy storage heat exchanger 140 and the energy storage medium 130 can be increased, thereby improving the heat exchange efficiency.

[0082] In some embodiments, such as Figure 1 shown, the accommodation cavity is filled with a phase change energy storage medium 130.

[0083] The energy storage heat exchanger 140 uses a phase change material as the energy storage medium. A phase change material is a substance that can absorb or release a large amount of latent heat at a specific temperature. When the phase change material changes from one phase state to another, such as from solid to liquid or from liquid to solid, significant heat absorption or release will occur.

[0084] The phase change energy storage medium 130 can be an organic phase change heat storage material, such as paraffin, fatty acid, etc., or an inorganic phase change heat storage material, such as crystalline hydrated salts, molten salts, alloys, etc., or a composite phase change heat storage material.

[0085] The phase change energy storage medium 130 is filled in the accommodation cavity. When the energy storage medium 130 stores thermal energy, the phase change material will absorb heat and undergo a phase change, such as melting from solid to liquid, thereby storing the thermal energy. When the energy storage medium 130 releases thermal energy, the phase change material will undergo a reverse phase change, such as solidifying from liquid to solid, and release the stored heat during this process.

[0086] At the same time, the latent heat of phase change absorbed or released by the phase change material during the phase change process is much greater than the heat released or absorbed by the material of the same mass during a certain temperature change process, and the overall temperature of the material remains constant during the phase change process, with a stable temperature thermal boundary condition. Corresponding to different usage scenarios, materials with different phase change temperatures can be selected. When the demand is for the cold storage working condition, a cold storage material with a phase change temperature of 4 - 16 °C can be selected for filling according to specific requirements. When the demand is for the heat storage working condition, a heat storage material with a phase change temperature of 60 - 95 °C can be further selected for filling according to specific requirements.

[0087] It can be understood that the phase change energy storage medium 130 has a high energy storage density and a constant energy storage and energy release temperature, and can also store or release a large amount of thermal energy within a small temperature change range.

[0088] In some embodiments, as Figures 1-3 shown, the accumulator 120 is provided with an energy storage medium loading port 121 and an energy storage medium unloading port 122 that communicate with the accommodation cavity to allow the replacement of the energy storage medium 130 according to different application requirements.

[0089] Among them, the energy storage medium loading port 121 is used to inject or fill new energy storage medium 130 into the accommodation cavity of the accumulator 120, and the energy storage medium unloading port 122 is used to empty or discharge the old energy storage medium 130 in the accommodation cavity. The energy storage medium loading port 121 can make the energy storage medium 130 fully and evenly distributed in the accommodation cavity to achieve the best thermal energy storage and release effect. The energy storage medium unloading port 122 can empty the medium safely and efficiently and prevent the medium from leaking or polluting the environment.

[0090] When the vehicle leaves the factory, a kind of energy storage medium 130 is filled according to the specific application scenario. For example, a cold storage material is filled in areas with higher ambient temperatures, and a heat storage material is filled in areas with lower ambient temperatures. When the energy storage medium 130 needs to be replaced, the old energy storage medium 130 can be discharged through the energy storage medium unloading port 122, and then a new energy storage medium 130 can be filled through the energy storage medium loading port 121.

[0091] In addition, the energy storage medium loading port 121 can also act as a pressure relief valve interface during normal use to prevent the overpressure risk that may occur during the energy storage process.

[0092] It can be understood that the accumulator 120 is provided with an energy storage medium loading port 121 and an unloading port communicating with the accommodating cavity, which can meet the requirements of medium replacement and adjustment under different application needs.

[0093] In some embodiments, such as Figure 2 and Figure 3 shown, the vehicle body structure 1 includes at least one of a door, a roof, a chassis, and a center console.

[0094] The door is an important part of the vehicle body structure 1, mainly used to provide a passage for passengers to enter and exit the vehicle, and also undertakes multiple functions such as protecting passenger safety, sound insulation, and dust prevention. The roof is also one of the key elements of the vehicle body structure 1. The roof is located at the top of the vehicle, providing shelter and protection for passengers, and at the same time jointly defining the internal space of the vehicle with other parts of the vehicle body. The chassis is the basic part of the vehicle. The chassis supports the entire vehicle body and the powertrain, and is responsible for the stability and controllability of the vehicle under various road conditions. The chassis usually includes multiple key components such as a frame, a suspension system, and a transmission system. The center console does not directly constitute the physical structure of the vehicle body, but the center console integrates various control and display functions, such as audio, air conditioning, navigation, etc.

[0095] The vehicle body structure 1 includes an outer covering 11 and an energy storage structure 10 installed inside the outer covering 11. The energy storage structure 10 can be installed on the door or the roof, or can be installed on the chassis through certain structural adjustments. At this time, positions such as inside the upper trim panel of the center console can be used as a radiation heat exchange module. For example, other structures in the energy storage structure 10 except the heat conduction structure 160 and the heat insulation member 150 are installed on the chassis, and the heat conduction structure 160 and the heat insulation member 150 are installed inside the upper trim panel of the center console.

[0096] It can be understood that the energy storage structure 10 can be installed on the door or the roof, or can be installed on the chassis and the center console through certain structural adjustments.

[0097] The embodiment of the present application also provides a vehicle, including: a vehicle body structure 1, an air conditioning system, and a heat exchanger 3, wherein the air conditioning system includes an evaporator 201 and a condenser.

[0098] The vehicle body structure 1 is the basic framework of the vehicle, which is used to carry other components of the vehicle and provide protection and shelter for passengers and other components of the vehicle. The air conditioning system is a system used to regulate the temperature and humidity inside the vehicle, which can provide a comfortable riding environment for passengers.

[0099] The evaporator 201 is a refrigeration component in the air conditioning system, which reduces the temperature inside the vehicle by absorbing the heat inside the vehicle. The condenser releases the heat absorbed by the evaporator 201 to the outside of the vehicle, usually by the air flow outside the vehicle to take away the heat. The specific working process is that the liquid refrigerant absorbs heat and evaporates into a gas in the evaporator 201, the gaseous refrigerant flows to the condenser to release heat and condenses into a liquid, and then flows back to the evaporator 201 to form a complete heat exchange cycle.

[0100] The heat exchanger 3 is usually used to transfer heat between different systems or media in the vehicle. The first path of the heat exchanger 3 is connected to the heat exchange medium inlet and the heat exchange medium outlet, that is, the heat exchange medium flows in the first path of the heat exchanger 3. The second path of the heat exchanger 3 is selectively connected in parallel with at least one of the evaporator 201 and the condenser. When the second path of the heat exchanger 3 is connected to the evaporator 201, the refrigerant circulates in the loop formed by the heat exchanger 3 and the evaporator 201, that is, the heat exchanger 3 and the evaporator 201 work simultaneously. When the second path of the heat exchanger 3 is connected to the condenser, the refrigerant circulates in the loop formed by the heat exchanger 3 and the condenser, that is, the heat exchanger 3 and the condenser work simultaneously. When the second path of the heat exchanger 3 is connected in parallel with the evaporator 201 and the condenser, the refrigerant circulates simultaneously in the loop formed by the heat exchanger 3 and the evaporator 201 and the loop formed by the heat exchanger 3 and the condenser, that is, the heat exchanger 3, the evaporator 201 and the condenser work simultaneously.

[0101] It can be understood that the air conditioning system and the heat exchanger 3 in the vehicle are interrelated, and the two work together to maintain the comfort inside the vehicle and the normal operation of each system of the vehicle. Among them, the air conditioning system adjusts the temperature inside the vehicle through the evaporator 201 and the condenser. The heat exchanger 3 can optimize the heat transfer path according to different working conditions and requirements through its flexible parallel connection design, so as to improve the working efficiency of the system.

[0102] In some embodiments, as Figure 5 shown, when the air conditioning system is in a refrigeration cycle, the condenser is the external condenser 202, and the second path of the heat exchanger 3 is selectively connected in parallel with the evaporator 201.

[0103] When the air-conditioning system is in the refrigeration cycle, i.e., under high-temperature conditions, the energy storage medium 130 used in the energy storage structure 10 is a low-temperature phase-change material with a phase-change temperature of 7°C. The condenser is the external condenser 202 of the vehicle, and the second path of the heat exchanger 3 is selectively connected in parallel with the evaporator 201.

[0104] When the vehicle is in the charging state, turn on the air-conditioning refrigeration cycle, i.e., turn on the electronic compressor 204, the electronic fan 208, the first electronic expansion valve 206, and the blower 211. When the electronic hygrometer 212 detects that the water vapor humidity at the current air outlet is less than the saturated water vapor humidity corresponding to the phase-change temperature of 7°C of the energy storage medium 130, start the water pump 13, open the solenoid valve 205 and the second electronic expansion valve 207, and take away the heat in the circulating water path through the heat exchanger 3. When the temperatures measured by the corresponding temperature sensors 12 in each energy storage structure 10 are all less than or equal to 5°C, it is considered that the cooling capacity is full at this time, and the solenoid valve 205, the second electronic expansion valve 207, and the water pump 13 are closed.

[0105] When the vehicle is in the driving state, after the humidity at the air outlet of the air conditioner is detected to meet the standard, open the heat insulation member 150 in the energy storage structure 10 to enable the temperature equalizing member 161 to perform radiative heat exchange with the passenger compartment. The heat of the object with a temperature higher than the surface temperature of the temperature equalizing member 161 will be gradually taken away. At this time, gradually reduce the air volume at the air outlet of the air conditioner, so that the energy storage structure 10 gradually replaces the operation of the air conditioner, reduce the noise and the blowing air volume on the face brought by the blower 211, improve the riding comfort of the vehicle, and can also reduce the power consumption of the air conditioner and improve the cruising range achievement rate.

[0106] In some embodiments, as Figure 6 shown, when the air-conditioning system is in the heating cycle, the condenser is the internal condenser of the vehicle, and the second path of the heat exchanger is selectively connected in parallel with the internal condenser of the vehicle.

[0107] When the air-conditioning system is in the heating cycle, under low-temperature conditions, the energy storage medium 130 used in the energy storage structure 10 is a high-temperature phase-change material with a phase-change temperature of 85°C. The condenser is the internal condenser 203 of the vehicle, and the second path of the heat exchanger 3 is selectively connected in parallel with the internal condenser 203 of the vehicle.

[0108] When the vehicle is in the charging state, turn on the air-conditioning heating cycle. During heating, the relative humidity inside the vehicle gradually decreases, and no condensation water will accumulate, so heat storage can be directly started. Turn on the electronic compressor 204, the solenoid valve 205, the first electronic expansion valve 206, the electronic fan 208, the blower 211, the three-way valve 213, and the water pump 13. The circulating water path obtains heat from the heat exchanger 3 and transfers it to the energy storage medium 130 in the energy storage structure 10. When the temperatures measured by the temperature sensors 12 in each energy storage structure 10 are all greater than or equal to 87°C, it is considered that the phase-change material has been completely transformed and the energy storage is completed. Then, close the solenoid valve 205, the three-way valve 213, and the water pump 13.

[0109] When the outside temperature is too low and the heat pump system cannot effectively obtain heat from the air, the liquid heater 14 can be turned on to assist in heating the liquid in the circulation pipeline, thereby increasing the energy storage speed.

[0110] When the vehicle is in motion, the heat insulation member 150 on the energy storage structure 10 can be opened, enabling the temperature equalizing member 161 to perform radiative heat exchange with the passenger compartment, so as to replace the air-conditioning blower 211 to supply heat to the vehicle interior. When the radiative heat exchange amount is sufficient, the air-conditioning windshield is closed. At this time, there is no blowing air to the face and the corresponding wind noise, and the comfort of the passenger compartment is greatly improved. When the ambient temperature is too low, part of the air-conditioning heating is then turned on.

[0111] In some embodiments, as Figure 7 shown, when the air-conditioning system is in a refrigeration cycle, the condenser is the out-of-vehicle condenser 202, and the second path of the heat exchanger can be selectively connected in parallel with the evaporator 201; when the air-conditioning system is in a heating cycle, the condenser is the in-vehicle condenser 203, and the second path of the heat exchanger 3 can be selectively connected in parallel with the in-vehicle condenser 203.

[0112] The working modes of the air-conditioning system are divided into a refrigeration cycle and a heating cycle. The connection modes of the condenser and the second path of the heat exchanger are different in the two modes. The switching between the refrigeration cycle and the heating cycle can be achieved by controlling the opening and closing state of the three-way valve 213.

[0113] In the refrigeration cycle, the main objective of the air-conditioning system is to lower the temperature inside the vehicle. At this time, the condenser is placed outside the vehicle, which is the out-of-vehicle condenser 202, and is used to release the heat absorbed by the evaporator 201 inside the vehicle to the external environment to achieve the cooling effect. In this mode, the second path of the heat exchanger 3 can be selectively connected in parallel with the evaporator 201 to complete the cold storage of the energy storage structure 10 in the refrigeration cycle.

[0114] In the heating cycle, the main objective of the air-conditioning system is to increase the temperature inside the vehicle. At this time, the condenser is placed inside the vehicle, which is the in-vehicle condenser 203, and is used to transfer the heat from the external environment or the heat generated by other means to the vehicle interior to achieve the heating effect. In this mode, the second path of the heat exchanger 3 can be selectively connected in parallel with the in-vehicle condenser 203 to complete the heat storage of the energy storage structure 10 in the heating cycle.

[0115] It can be understood that the refrigeration and heating cycles are usually mutually exclusive, that is, only one cycle can be carried out at the same time. In practical applications, the connection mode of the second path of the heat exchanger 3 will be determined according to the working mode.

[0116] In some embodiments, as Figures 5-7 shown, there are multiple energy storage structures 10, and the multiple energy storage structures 10 are connected in parallel.

[0117] In a circuit, parallel connection means that the positive and negative poles of multiple components are connected together respectively, enabling the current to be divided and pass through each component. At a broader system level, parallel connection generally refers to the connection of multiple subsystems or components in such a way that each component operates independently but jointly serves the function of the entire system.

[0118] The energy storage structure 10 is a device capable of storing and releasing energy. Each energy storage structure 10 is independent. In the case of multiple energy storage structures 10 connected in parallel, when one energy storage structure 10 fails, the other energy storage structures 10 can still continue to operate, thereby improving the reliability of the entire system.

[0119] Connecting multiple energy storage structures 10 in parallel can significantly increase the total energy that the system can store and release, and can also adjust the working state of each energy storage structure 10 according to actual needs. For example, when the energy demand is low, the number of working energy storage structures 10 can be reduced to save resources, and when the energy demand peaks, all energy storage structures 10 can be started to meet the demand.

[0120] It can be understood that connecting multiple energy storage structures 10 in parallel is an efficient, reliable and flexible energy storage method that can meet the energy storage and release requirements in various complex application scenarios.

[0121] In some embodiments, as Figure 4 shown, the energy storage structures 10 located in different vehicle body structures 1 are connected through the A-pillar 15, B-pillar 16 or C-pillar 17.

[0122] The A-pillar 15, B-pillar 16 or C-pillar 17 are mainly key supporting components of the vehicle body structure 1, but the internal space or the area nearby can be used as a channel for connecting different energy storage structures 10. The energy storage structures 10 located in different vehicle body structures 1 can be connected through the A-pillar 15, B-pillar 16 or C-pillar 17, or structural members arranged along the bottom, side or top of the vehicle body can also be used.

[0123] It can be understood that the area where the A-pillar 15, B-pillar 16 or C-pillar 17 are located can be used as a potential path for connecting the energy storage structures 10 located in different vehicle body structures 1, or special connecting pieces can also be used to achieve the connection between the energy storage structures 10 to ensure the integrity of the vehicle body structure 1 and the efficiency of energy transmission.
